Categorical logic is the branch of mathematics in which tools and concepts from category theory are applied to the study of mathematical logic. ... In broad terms, categorical logic represents both syntax and semantics by a category, and an interpretation by a functor.
What branch of math is category theory?
Category theory has come to occupy a central position in contemporary mathematics and theoretical computer science , and is also applied to mathematical physics. Roughly, it is a general mathematical theory of structures and of systems of structures.

What’s the use of category theory?
Category theory has practical applications in programming language theory , for example the usage of monads in functional programming. It may also be used as an axiomatic foundation for mathematics, as an alternative to set theory and other proposed foundations.
What is a logical category?
Category, in logic, a term used to denote the several most general or highest types of thought forms or entities , or to denote any distinction such that, if a form or entity belonging to one category is substituted into a statement in place of one belonging to another, a nonsensical assertion must result.
What is category example?
The definition of a category is any sort of division or class. An example of category is food that is made from grains . A class or division in a scheme of classification.
Is category theory just graph theory?
Category theory draws from graph theory that we may talk about dots being connected, the degree of a dot etc. And when we do not have an extremly huge amount of dots, a category is a graph. So in this case Category theory is just a special case of graph theory .
